Thanks for the tip on needing to shade the outline, and making the images of course. I'd seen a few people using pictures so I thought maybe the outline would be okay.

You're right about the axle bumps. I'd tried to estimate the height of the engine/transmission across the front of the car but I got it a little low, the actual height is just about exactly where the OE chin air dam is in the top image in your composite and the rear bump really doesn't need to be there at all.

If I'm reading these images right it looks like air dam and no spoiler (Bottom image) is slightly better than the stock setup and air dam and Cavalier spoiler (3rd from top) is the best of the three non-stock options?

Not shown here is the trailer hitch installed on the car. I use it too often and it's too much of a PITA for me to remove even though it's dead weight the rest of the time. It doesn't hang down below the bodywork though and it would make a good mounting point for pan of some sort at the rear that I could tuck up onto the lower lip of the rear bumper cover.
